Product description： RACOFIBERCalcium silicate board 1050℃ is also named porous calcium silicate board, composed of calcium carbide water compound and reinforced fibers. Its asbestos-free and the maximum thermal temperature can reach 1050℃, its a kind of high efficiency and energy saving insulating product.
Features: Good durability and can withstand the continuous heat load in high temperature limit. Low thermal conductivity and fantastic heat thermal insulating performance. Light weight and high rupture and compressive strength. Easy to install and can be optionally cut by normal instruments. Used safety, cleanly and totally free from asbestos, sulfur and chlorine. Water-fast, quality maintained after dry. Increase the service life and protect the high temperature equipment.
